Homatropine methylbromide_product_DataBase

Bioactivity	Homatropine methylbromide (Homatropine methobromide) is muscarinic AChR antagonist, inhibits endothelial and smooth muscle muscarinic receptors of WKY-E and SHR-E with IC50 of 162.5 nM and 170.3 nM, respectively.
Target	IC50: WKY-E (162.5 nM), SHR-E (170.4 nM)
Invitro	Homatropine methylbromide (Homatropine methobromide) (20 μM) alone produces a dose ratio of 259 in atrium from guinea-pigs. Homatropine methylbromide (Homatropine methobromide) (20 μM) produces a dose ratio of only 95.0 when combined with hexamethonium in atrium from guinea-pigs.
In Vivo	Pre-treatment with Homatropine methylbromide (Homatropine methobromide) (20 mg/kg) was comparable with atropine (10 mg/kg) in preventing lethality in this rat model of acute OC poisoning.
